Sienna Miller is on a style roll, making waves with her impeccable fashion choices. From the stunning sheer gown by Annie’s Ibiza she donned at a friend’s birthday party last week to her full-on Boho revival at the Chloé show in March, Miller is redefining effortless chic. The latest buzz? Sienna Miller is back with another Marks & Spencer collaboration, and this time, it’s brimming with summery boho heroes inspired by her own iconic wardrobe. For nostalgic Noughties fans, this is nothing short of a fashion dream come true.
We’re already predicting this new line will be a sell-out success, making it one of the most exciting high-street collaborations in recent memory—even surpassing the much-hyped Mango x Victoria Beckham line. This collection perfectly taps into the boho revival trend championed by Chloé’s new creative director, Chemena Kamali. Naturally, Sienna was front row at Kamali’s headline-grabbing AW24 Fashion Week show, fully embracing the boho aesthetic.
The British actress, model, and all-around style icon has once again lent her effortless cool to M&S, just in time for festival season. You can shop this must-have collection starting Thursday, June 6, online and in Dublin Grafton Street. With prices ranging from £29.50 to £89, this refreshingly affordable line makes high fashion accessible to all. Set your alarms now, because you won’t want to miss out!
The M&S x Sienna Miller collection is packed with timeless pieces that will seamlessly integrate into your existing capsule wardrobe. It embraces the ‘high/low dressing’ ethos—pairing luxe items with everyday essentials—that Sienna herself exemplifies on the red carpet, at events, and on the school run.
Expect nods to summer festivals, with pieces like a coin belt that pays homage to Sienna’s iconic Glastonbury look. The collection also features Seventies prints, exotic adventure vibes, and some of Sienna’s favourite vintage finds. One standout item is a printed shift dress, nearly an exact replica of a sixties style she discovered in a New York thrift store. An ombre slip dress in the collection is reminiscent of the slinky Galvan number she often sports.
With 33 gorgeous pieces to choose from, including Sienna’s ‘dress of the season’—a chic ruffled maxi dress available in ivory and pale blue—there’s something for everyone. The pale blue version, in particular, is poised to become a wedding guest favourite. The collection is characterized by fluid lines, rich textures, and vintage-inspired fabrics, with each item telling a story and referencing famous looks from Sienna’s fashion archives.
This collaboration is a labour of love for Sienna, with her fashion fingerprints all over it. Whether you’re heading to a festival, a summer wedding, or just looking to inject some boho chic into your wardrobe, the M&S x Sienna Miller collection has you covered.
